Full Band Noise Figure and Gain Test Extenders
STG-06-S1
-
Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.

Noise Source, 1 GHz up to 50 GHz
346CK01
-
The Keysight 346CK01 is the ideal companion to Keysight´s noise figure solutions when working on high frequency applications. Since it is broadband (1 GHz to 50 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty, which are reflections of the test signals. This is a coaxial noise source with a 2.4 mm coaxial connector. ENR typically 20 dB at 1 GHz, decreasing to typically 7 dB at 50 GHz.
